The Prophet ﷺ said, "If somebody claims to be the son of any other than his real father knowingly, he but disbelieves in Allah, and if somebody claims to belong to some folk to whom he does not belong, let such a person take his place in the (Hell) Fire."  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ لَيْسَ مِنْ رَجُلٍ ادَّعَى لِغَيْرِ أَبِيهِ وَهْوَ يَعْلَمُهُ إِلاَّ كَفَرَ وَمَنِ ادَّعَى قَوْمًا لَيْسَ لَهُ فِيهِمْ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ  

Indeed what prevents me from relating to you a great number of Ḥadīth is that the Messenger of Allah ﷺ said: ‘Whoever intends to lie upon me, then let him take his seat in the Fire."  

أَنَّهُ قَالَ إِنَّهُ لَيَمْنَعُنِي أَنْ أُحَدِّثَكُمْ حَدِيثًا كَثِيرًا أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ تَعَمَّدَ عَلَىَّ كَذِبًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ  

[Machine] He heard the Prophet ﷺ saying, "Whoever invents a lie about me, let him take his place in Hellfire."  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ «مَنْ حَدَّثَ عَنِّي كَذِبًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ»  

[Machine] The Messenger of Allah ﷺ said, "Whoever allies himself with someone other than his allies, he should take his place in the fire."  

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ تَوَلَّى إِلَى غَيْرِ مَوَالِيهِ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ»  

"مَن ادَّعَى ما لَيس لَهُ فَلَيسَ مِنَّا ولْيَتَبوَّأ مقْعده مِن النَّار".  

"مَنْ تَوَلَّى عَمَلًا وَهُوَ يَعْلَمُ أَنَّهُ لَيسَ لِذَلِكَ الْعَمَلِ أَهْلٌ فَليَتَبَوَّأْ مَقْعَدَهُ مِن النَّارِ".
